* download file * download containers * fix push image to nodes * pull if none image on host * fix * improve docker image tag checks. do not pull already cached images * rebase fix merge conflict * add support download_run_once when upgrade and scale cluster add some test with download_run_once * set default values to temp flag for every download cycle * add save,load abilty for containerd and crio when download_run_once=true * return redefine image save/load command to set_docker_image_facts.yml * move set command to set_container_facts * ctr in containerd_bin_dir * fix order of ctr image export arguments * temporary disable download_run_once for containerd and crio due https://github.com/containerd/containerd/issues/4075 * remove unused files * fix strict yaml linter warning and errors * refactor logical conditions to pull and cache container images * remove comment due lint check * document role * remove image_load_on_localhost, because cached images are always loaded to docker on remote sites * remove XXX from debug output
